How SSA defines "Substantial Gainful Activity"
Under 42 U.S.C. § 423(d)(1)(A), disability means the inability to engage in any substantial gainful activity by reason of a medically determinable impairment expected to last 12 months or result in death. SSA uses a monthly earnings threshold to measure SGA, updated annually under 20 C.F.R. § 404.1574.
For 2026, SGA is $1,620/month for non-blind claimants and $2,700/month for statutorily blind claimants. Both numbers are gross earnings before taxes. In-kind compensation, tips, and employer-paid subsidies all count.
SGA is a bright line
One month at $1,700 in 2026 is enough for a Step 1 denial. SSA does not average across the year and does not care how sick you felt that month — the pay stub is what counts.
Self-employment: it's more than earnings
Self-employed applicants are evaluated under three tests in 20 C.F.R. § 404.1575:
- Significant services and substantial income. Whether you provide meaningful services to a business that produces sufficient income.
- Comparability of work. Whether your work is comparable to that of unimpaired self-employed workers in the community.
- Worth of work. Whether your work is worth the SGA earnings amount when performed at a competitive rate.
This means low net earnings do not automatically save a self-employed claim. If you are running a business full-time, SSA can find SGA even if the business loses money.
Unsuccessful work attempts (UWAs)
An unsuccessful work attempt is a short-lived return to work that ended because of the impairment. Under 20 C.F.R. § 404.1574(c), if the work lasted no more than 6 months and ended or dropped below SGA because of the disability (or the elimination of special conditions), the earnings are ignored for the SGA analysis. Document the medical reason work stopped — a discharge summary, treating-source note, or resignation letter — carefully.
Subsidies and impairment-related work expenses
Not every dollar on your pay stub counts toward SGA. Two deductions can lower reported earnings:
- Employer subsidy. If your employer pays you more than the real value of the work you perform — because of a special arrangement, reduced productivity, or accommodations — the subsidy portion is deducted (20 C.F.R. § 404.1574(a)(2)).
- Impairment-related work expenses (IRWEs). The cost of items or services needed to work because of your impairment (medications, adaptive equipment, transportation you would not otherwise need) is deducted under 20 C.F.R. § 404.1576.
After approval — the Trial Work Period
Once you are approved, SSDI encourages return-to-work attempts through the Trial Work Period (TWP) under 20 C.F.R. § 404.1592. You may work 9 months (not necessarily consecutive) in a rolling 60-month window at any earnings level without losing benefits. In 2026, a month counts as a "TWP month" only if earnings exceed $1,160. After the TWP, a 36-month Extended Period of Eligibility begins, during which benefits are paid in any month earnings fall below SGA.
Reporting rules and overpayments
You must report work, hours, and earnings to SSA promptly. Failure to report can trigger overpayment demands, benefit suspension, and — in extreme cases — fraud investigation under 42 U.S.C. § 408. Save every pay stub. Use the SSA mobile wage reporting app or the my Social Security account online.
